Ezo fire, 4 January 2026 Ezo, Nzara, Tambura

Out · last detection 18 Jan 2026, 11:43 UTC

The fire started on 4 January 2026 in Ezo, South Sudan, and satellites saw it burning for 14 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 15,313 hectares from heat detections, spread across 3 municipalities.

It is the 76th largest in Western Equatoria since 2016 (of 361 with a page). Number 23 in South Sudan in 2026, of 183.

This area had burned before

84% of the perimeter overlaps earlier fires recorded since 2016: 5,508 ha in 2016, 3,917 ha in 2017, 446 ha in 2018, 486 ha in 2019, 5,581 ha in 2020, 1,381 ha in 2021, 1,699 ha in 2022, 993 ha in 2023, 1,056 ha in 2024, 8,513 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 12,848 ha that had burned before.

How big is it?

10 km
It burned the equivalent of 9.7% of the area of London (153 km² against 1,583 km²).

Frequently asked questions

How long did the Ezo fire last?
GWIS (Copernicus) dates it between 4 January 2026 and 17 January 2026: 14 days between the first and last heat detection of the perimeter.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 15,313 hectares (153.1 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 3 municipalities: Ezo (10,758 ha, 1.3 %); Nzara (2,516 ha, 0.4 %); Tambura (2,137 ha, 0.2 %).
What was the weather like?
During the fire the temperature reached 36.8 °C, humidity dropped to 16 % and gusts hit 41 km/h. The fire danger index (FWI) reached 51, class Extreme.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of South Sudan (geoBoundaries). It is not an official report.

Where to verify it

A satellite detection is not an official report. Final figures and the fire’s status are published by each country’s emergency service.

Satellite cross-check

Does something look wrong on this page?

This page is built from satellite data and official records, and it sometimes gets things wrong: the wrong dates, the wrong town, two fires merged into one, or something that was not a wildfire at all. If you know this fire first-hand (you live nearby, saw it, fought it or reported on it), tell us what really happened and we will check it.

How we know this
  • Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery; 2 polygons grouped in this page.
  • Dates from the perimeter: the VIIRS detections inside it did not change them. 374 Suomi-NPP VIIRS detections on those dates.
  • We have not matched this page with any official record.
  • Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.

Where this data comes from

The perimeter comes from the Copernicus Global Wildfire Information System (GWIS), which rebuilds it from MODIS and VIIRS heat detections and publishes it under CC BY 4.0. It is not measured on imagery as in Europe, so it is an estimate. Heat detections come from the VIIRS sensors aboard Suomi-NPP and NOAA-20, distributed by NASA FIRMS at 375 m resolution. Municipal boundaries come from geoBoundaries ADM2 (Creative Commons Attribution 3.0 Intergovernmental Organisations (CC BY 3.0 IGO)). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ from each country’s official figure.
